Vulnerability from gsd - Updated: 2021-05-05 00:00

Details

There is a possible DoS vulnerability in the Token Authentication logic in Action Controller. This vulnerability has been assigned the CVE identifier CVE-2021-22904. Versions Affected: >= 4.0.0 Not affected: < 4.0.0 Fixed Versions: 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 Impact ------ Impacted code uses `authenticate_or_request_with_http_token` or `authenticate_with_http_token` for request authentication. Impacted code will look something like this: ``` class PostsController < ApplicationController before_action :authenticate private def authenticate authenticate_or_request_with_http_token do |token, options| # ... end end end ``` All users running an affected release should either upgrade or use one of the workarounds immediately. Releases -------- The fixed releases are available at the normal locations. Workarounds ----------- The following monkey patch placed in an initializer can be used to work around the issue: ```ruby module ActionController::HttpAuthentication::Token AUTHN_PAIR_DELIMITERS = /(?:,|;|\t)/ end ```

Vulnerability from github – Published: 2021-05-05 19:49 – Updated: 2023-08-08 16:06

Summary

Possible DoS Vulnerability in Action Controller Token Authentication

Details

There is a possible DoS vulnerability in the Token Authentication logic in Action Controller.

Versions Affected: >= 4.0.0 Not affected: < 4.0.0 Fixed Versions: 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6

Impact

Impacted code uses authenticate_or_request_with_http_token or authenticate_with_http_token for request authentication. Impacted code will look something like this:

class PostsController < ApplicationController
  before_action :authenticate

  private

  def authenticate
    authenticate_or_request_with_http_token do |token, options|
      # ...
    end
  end
end

All users running an affected release should either upgrade or use one of the workarounds immediately.

Releases

The fixed releases are available at the normal locations.

Workarounds

The following monkey patch placed in an initializer can be used to work around the issue:

module ActionController::HttpAuthentication::Token
  AUTHN_PAIR_DELIMITERS = /(?:,|;|\t)/
end

Patches

To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset.

5-2-http-authentication-dos.patch - Patch for 5.2 series
6-0-http-authentication-dos.patch - Patch for 6.0 series
6-1-http-authentication-dos.patch - Patch for 6.1 series

Please note that only the 6.1.Z, 6.0.Z, and 5.2.Z series are supported at present. Users of earlier unsupported releases are advised to upgrade as soon as possible as we cannot guarantee the continued availability of security fixes for unsupported releases.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
